ADI AD8315ACP-REEL7

DCS, GSM, EDGE100MHz ~ 2.5GHz

Overview

The AD8315ACP-REEL7 is a complete low cost subsystem for the precisecontrol of RF power amplifiers operating in the frequency range0.1 GHz to 2.5 GHz and over a typical dynamic range of 50 dB.It is intended for use in cellular handsets and other batteryoperatedwireless devices. The log amp technique provides a muchwider measurement range and better accuracy than controllersusing diode detectors. In particular, the temperature stability isexcellent over a specified range of −30°C to +85°C.

The AD8315ACP-REEL7 is available in MSOP and LFCSP packages andconsumes 8.5 mA from a 2.7 V to 5.5 V supply. When powereddown, the sleep current is 4 μA.
